TABLE OR CABINET FOR 'SEWING-MACHINES.

SPECIFICATION formingpart of Letters Patent N o. 590,417, datedSeptember 21, 1897.

Application filed June 1, 1897. Serial No. 638,956. (No model.)

To @ZZ whom t may concern,.-

Be it known that 1, THEoDoR KUND'rz, of Cleveland, Cuyahoga county,Ohio, have invented certain new and useful Improvements in Tables orCabinets for Sewing-Machines, dsc. 5 and I do hereby declare thefollowing to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

My invention relates to improvements in tables or cabinets forsewing-machines, ttc.

The primary object of my invention is to provide novel and desirablemechanism for actuating the tilting leaf that bears the sewing-machinehead or other machine; and the invention consists in certain features ofconstruction and conibinations'of parts hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure I is a top plan of a table orcabinet embodying my. invention. Portions are broken away and in sectionin this figure to more clearly show the construction. The load -bearingtilting leaf in this figure is shown in its horizontal or elevatedposition. Fig. II is an end elevation, partly in vertical section, online II II, Fig. I. Fig. III is an end elevation, partly in verticalsection, and shows the said tilting leaf in its downwardly-tilted orlowered position.

Referring to the drawings, A designates the top of the table or cabinet.Top A is provided centrally with a rectangular opening a, that extendsthrough the top. A verticallytilting leaf B is arranged to enter andoccupy said opening and is horizontally hinged o1' pivoted at its rearend at B' to and longitudinally of top A at the rear end of opening c.MemberB is known as the load-bearingleaf 7 and carries thesewing-machine head or other machine (not shown) of the table orcabinet.

hen the machine is not in use, leaf B is tilted downwardly below top Aand is again tilted upwardly or elevated into opening' a when themachine is required for use. Said leaf B is operatively connected withthelifting-leaf C, that is horizontallyhinged at one end, as at C", toand transversely of the lefthand end of top A. The arrangement of partsis such that when said leaf C is in a horizontal position and forms aleftward eX- tension of top A leaf 'B is in its elevated position, andwhen leaf C closes opening ct and rests upon top A the load-bearing leafB is in its downwardly-tilted position and the lastmentioned leaf iselevated or lowered according as the lifting-leaf C is tilted to theleft or right.v y

The novel and meritorious mechanism eniployed in establishing operativeconnection between the load-bearing leaf B and the lifting-leaf Ccomprises, preferably, the following: The rear side or back A of thecabinet or table, at its left-hand end, is provided with a vertical orupright slideway a'. A slide D engages and is adapted to reciprocateendwise of said slideway. Slide D has an upwardly-l projecting arm d,that is connected, by means of a stiff` metallic link d', with the rearportion of the hinged end of the lifting-leaf C- that is, one end ofsaid link is pivoted horizontally at cl2 to arm d of the slide, and thelinks opposite end is pivoted horizontally at d3 to the lifting-leaf.Top A and the liftingleaf C are suitably slotted or mortised, as at E,to accommodate the location and operation of said link and slide. Alifting-lever G, that is arranged below the left`- hand end andtransversely of top A, has its rear and power end operatively attachedto slide D and at its forward end is fulcrumed at G horizontally andlongitudinally of top A to a bracket or member A2, depending fromv andrigid with the forward portion of said top. A roller or wheel b issupported from and below the lefthand end of the load-bearing leaf B andrests upon said lever, and consequently said leaf is elevated or loweredaccording as the lever is tilted upwardly or downwardly, and the leveris tilted downwardly or upwardly according as slide D is lowered orelevated, and said slide is elevated or lowered according as thelifting-leaf C is tilted to the left or to the right. The trend of thelifting-lever G is preferably such that its greatest lifting power isacquired after the lifting-leaf in actuating it from its closingposition into its other extreme position shall have been tilted throughabout one-third or more of the arc in which it is moved in tilting itfrom its closing position into its extreme opposite position. It willtherefore be observed that said lever at or near its central portion isprovided with IOO a forwardly and upwardly extending incline g, thatconnects the rear portion with the forward portion of thelifting-surface of said lever, and of course the lever exerts itsgreatest power when said incline is engaged by the roller or leaf Bduring the elevation of said leaf.

I-I designates a plate that is vertically pivoted at h to the under sideof the right-hand end of top A, as shown in dotted lines, Fig. I, and isarranged to render it capable of being actuated in under the load-bearing leaf B, so as to support the latter when said leaf is in itsupwardly-tilted position.

Of course the lifting-lever should have some play endwise, and this playis readily provided for by having the levers free end eX- tendingloosely through a hole in the slide or by having the levers fulcrumedend provided with a lon gitudinally-arranged slotG, through which theaxial pin or bearing extends.

That I claim isl. In a table or cabinet of the characterindicated, thecombination with the top A having an opening therethrough, theverticallytilting load carrying leaf B horizontally hinged or pivoted tosaid top and arranged to occupy the opening in the top in itsupwardlytilted position, and the lifting-leaf C hinged horizontally andtransversely of the cabinet at the left-hand end of the top of a slidemovable up and down below the top, a slideway for said slide, operativeconnection between said slide and the lifting-leaf, a lifting-leverhaving its free end operatively engaging the slide and having itsopposite end fulcrumed to a member of the table r cabinet, and a 'rollerresting upon said lever and supported from the load-carrying leaf,substantially as and for the purpose set forth.

2. In a table or cabinet of the character indicated, the combinationwith the top A provided with the opening a, the vertically-tiltingload-carrying leaf B horizontally hinged or pivoted to the top, and thelifting-leaf C hinged horizontally to and transversely of the left-handportion of said cabinet or table; of a slide D movable up and down belowthe rear portion of the aforesaid top, a slideway for said slide,operative connection between said slide and the lifting-leaf, a lever Grarranged below and transversely of the left-hand end of theload-carrying leaf, and having its rear end operatively engaging theslide and suitably fulcrumed at its forward end to a member of the tableor cabinet, and a roller or Wheel resting upon said lever and supportedfrom the aforesaid load-carrying leaf, substantially as and for thepurpose set fort-h.

3. In a table or cabinet of the character indicated, the combinationwith the top A provided with the opening a, the vertically-tiltingload-carrying leaf B horizontally hinged or pivoted to the top, and thelifting-leaf C hinged horizontally to and transversely of the left-handportion of said cabinet or table; of a slide D movable up and down belowthe rear portion of the aforesaid top, a slideway for said slide,operative connection between said slide and the lifting-leaf, a lever -Garranged below and transversely of the left-hand end of theload-carrying leaf, and having its rear end operatively engaging theslide and suitably fulcrumed at its forward end to a member of the table4or cabinet, a roller or wheel resting upon said lever and supportedfrom the aforesaid load-carrying leaf, and the bearing-surface of saidlever having the trend required to form the rearwardly and downwardlyextending incline g at or near the central portion of the lever,substantially as and for the purpose set forth.

Il. In a table or cabinet of the character indica-ted, the combinationwith the top A having the opening a, the load-carryin g leaf movabledownwardly below and upwardly into said opening, and the lifting-leaf Chinged at C to the left-hand end of the top; of the slide D having anupwardly-extending arm d; the vertically-arranged slideway a for saidslide; the link LZ horizontally pivoted at one end to the aforesaid arm,and horizontally pivoted, at its opposite end, to the lifting-leaf; asuitably-supported lever suitably arranged below and extendingtransversely of the lefthand end of the load-carrying leaf andoperatively engaging the slide, and the roller b arranged to rest andmove upon said lever and supported from the load-carrying leaf,substantially as shown, for the purpose specilied.

In testimony whereof I sign this specific'a- THEODOR KUNDTZ.
